Improve chain retention, reduce drivetrain wear, and keep your bike running smoothly with a fresh 104 BCD chainring.

We’ve designed the new 104 BCD ring to accommodate the added power and increased load from E-Bikes. The tooth profile eliminates chain drop and sheds mud. A simple upgrade you’ll notice every ride.

- Narrow-wide teeth prevent unwanted chain drop
- Perfect chainline with 2mm shims included with 32T and 34T rings (30T rings have built-in offset). For 2x crank conversions, shims between the crank and ring get you back to an ideal 49-50mm chainline
- Excellent mud-shedding performance for extended ring life
- Compatible with SRAM and Shimano 12-speed chains
- Made from 7075-T6 aluminum alloy
